2011 Lincoln MKT key bypass programming will not show red led when pressing brake pedal.

Question

I am trying to do the key bypass steps as described in the stand alone Evo All Lincoln MKT 2010-2014 installation instructions, but getting stuck after being told to insert the oem remote (without battery) into the keyport and press and  release the brake pedal to get the unit to display the red LED. The unit only continues to disply the yellow LED despite me pressing and releasing the brake pedal (waiting 5 seconds between each push) up to 50 times. I am using firmware .57, as instructed  in the instructions, and have flashed the unit mutiple times. I have also reset the unit and reflashed all to no avail.
